Otso Cycles hails from Burnsville, MN., which is a long ways from where the brand’s identity is rooted. In Finnish mythology, Otso is the Spirit of the Bear; the noble king of the forest, a spirit of strength and courage, and also a relative with whom we share our adventures in and out of the wilderness.
Voytek (Wojtek, meaning “Happy Warrior” in Polish) was a brown bear that in an interesting set of circumstances was enlisted in the Polish Army during WWII. Voytek was a happy warrior indeed; he drank beer, smoke (or ate) cigarettes, wrestled with the troops and carried 100-pound crates of ammunition into battle.
The sharp minds at Otso are also the brains that bring us Wolf Tooth Components and along with their unique brand identity, they appear to have put that same level of thought and detail into the Voytek Plus-Fat bike.
The Voytek is a carbon hardtail that accepts 27.5+, 29+ and 26 x 4.6 tires on up to 70mm rims (tire clearance is from Otso’s website… we’ll be playing around with different tire and wheel mashups during testing). One of the big stand-out features of the Voytek is the narrow Q-factor; 30-50mm narrower than typical for a fat-bike. If you’ve had to give up your fat-bike because of knee pain caused by the wide B.B., this could be your solution!
The rear dropout features Otso’s Tuning Chip, which allows the chainstay length to be changed from 430mm to 450mm. In our current testing mode, the Voytek fits a 27.5×4.0 Terrene Cake Eater on a 50mm rim in the shorter chainstay length. The tukt rear end plus some modern trail geometry promise to make this bike a ton of fun out on the trail.
Our test rig came boxed as carefully and professionally as I’ve seen. Expecting to see a previously ridden demo bike in the box, the sight of a brand new bike sort of blew my mind!

Otso does provide several different build options and price points for you to choose from when ordering as well.
The test rig came with two pairs of tires; a pair of Terrene McFly 2.8’s and a pair of Terrene Cake Eater 4.0’s. The idea here is with the Voytek’s “Plus – Fat” concept, you’ve got two bikes in one with a simple swap of the tires… 2.8 “plus” tires for trail ripping and the 4.0 “fat” tires for snow, sand, deep woods bushwacking, etc. Is this set-up a “quiver killer”? We’re fixin’ to find out!
Otso has been generous enough to grant us a long-term test on the Voytek Plus – Fat rally build, so we’ll be ripping it in the dirt through the rest of Summer and Fall until we can rip it in the snow come Winter time. Stay tuned, and happy trails!
